I have had several tanks ´start leaking´ on the ´leg´ at the front/bottom of the tank. May have been caused by Vibration through old/dried out ´tank rubber´. Get New Rubber (2 on bike frame under tank, one on front bolt, one around rear bolt) if yours is old and cracked. Trying to get one of these tanks welded/painted can be E X P E N S I V E! A new tank $1700! on Bike Bandit. Many ´replacement´ tanks just as bad.
